Lopes, André; João, Karen; Rubik, Djonatam; Bogel-Lukasik, Ewa; Duarte, Luís C.; Andreaus, Jurgen; Bogel-Lukasik, R.This work is devoted to study pre-treatment methodologies of wheat straw with 1-ethyl-3-methylimidazolium acetate ([emim][CH3COO]) and subsequent fractionation to cellulose, hemicellulose and lignin. The method developed and described here allows the separation into high purity carbohydrate and lignin fractions and permits an efficient IL recovery. A versatility of the established method was confirmed by the IL...
Ionic liquids as a tool for lignocellulosic biomass fractionation
Lopes, André; João, Karen; Morais, Ana Rita; Bogel-Lukasik, Ewa; Bogel-Lukasik, R.Lignocellulosic biomass composes a diversity of feedstock raw materials representing an abundant and renewable carbon source. In majority lignocellulose is constituted by carbohydrate macromolecules, namely cellulose and hemicellulose, and by lignin, a polyphenilpropanoid macromolecule. Between these biomacromolecules, there are several covalent and non-covalent interactions defining an intricate, complex and r...
Pretreatment and fractionation of wheat straw using various ionic liquids
Lopes, André; João, Karen; Bogel-Lukasik, Ewa; Roseiro, Luísa; Bogel-Lukasik, R.Pretreatment of lignocellulosic biomass with ionic liquids (ILs) is a promising and challenging process for an alternative method of biomass processing. The present work emphasizes the examination of wheat straw pretreatment using ILs, namely, 1-butyl-3-methylimidazolium hydrogensulfate ([bmim][HSO4]), 1-butyl-3-methylimidazolium thiocyanate ([bmim]-[SCN]), and 1-butyl-3-methylimidazolium dicyanamide ([bmim][N(...
Fractionation of wheat straw using ionics liquids as a tool of pre-treatment
Lopes, André; João, Karen; Bogel-Lukasik, R.The pre-treatment of lignocellulosic biomass with ILs is a promising and challenging process for an alternative method of biomass processing [1]. The high selectivity of ILs demonstrated to achieve a complete dissolution of all lignocellulosic components at mild conditions.
Pre-treatment of different types of lignocellulosic biomass using ionic liquids
João, Karen Andreína GodinhoDissertação apresentada na Faculdade de Ciências e Tecnologia da Universidade Nova de Lisboa para obtenção do grau Mestre em Biotecnologia ; The pre-treatment of biomass by ionic liquid (IL) is a method opening new possibilities of biomass fractionation for further valorisation of low value feedstock. This work is dedicated to study on the pre-treatment and fractionation of different types of lignocellulosic b...
